Customer Ratings & Reviews

Great Stuff.

Oil has performed very well and has not burned off in highly modified 700hp M5. I have run Redline and Moly in this car and the analysis of the oil after the first change has been superior to both.

Fast shipping

Oil looked almost the same color after 10k miles as when I put it in. Got slightly better milage with it, engine runs better with it. I just love it and will always use it.

All of the Amsoil oil products are outstanding(incl Trans and differential fluids). Outstanding wear and cooling characteristics. WISH they could solve their availability issues on oil filters.

Very satisfied with products

Ive been usuing the signiture series in my 2019 Ford Ranger from day one and couldn't be happier!! I run Amsoil in all my vehicles and in my motorcycles as well!! Good quality product!! Always inpressed!

After a bit of research I also started using the amsoil oilfilters gonna see if they have them for oil and fuel filters for my cummins aswell

Tried a few different synthetic oils in my ford 6.2 and always had kind of a slight tick, just changed over to this and it’s as quiet as a church mouse!!! Won’t run anything else now!

If you are familiar with most motor oil, this will be the last you ever buy.

Absolutely the best on the market. I use Amsoil in vehicles, lawn mowers, and even my standby generator. Has never let me down...........

I been using this for a very long time it keeps the engine clean.

I have a car that I used to use fir Uber/lyft, Now I don’t drive that car much, so i use this oil, one oil chance per year, I’m driving less than 20,000 miles a year for sure, save money stay protected

On my next Oil change I will be Replacing with this Oil, I intend to do one or two oil changes a year only as we don’t drive that much. If they had a filter that goes with this oil I woild buy it.

Best oil in the world. 2007 Prius: 200,000 miles and only added 1/4 quart in 19,000 miles. No motor wear, no sludge, no mechanic bills.

Was first introduced to AMSOIL by uncle a few years back. Have a 05 F150 XLT super-crew cab with that troublesome 54L 3 valve triton engine. Was starting to have to add about a quart of a oil every couple of weeks, granted the engine had 265,732 miles at the time. Uncle told me to use AMSOIL synthetic, and I should see a difference. I'll be damned if it didn't make a difference. After the initial oil change to the AMSOIL, it was probably a few when I checked my oil level, it was still where I had topped it off at. Don't know what additives they use, but definitely the engine ran smoother, no more oil loss between changes. Well, I just replaced that engine, the original engine in the truck, was at 275,586 miles, it was tired. Definitely starting the new engine out on the AMSOIL 5W-20 synthetic, if it made that much improvement to an old tired engine, I can just imagine the results I'll have with a brand new engine and AMSOIL right from start, the truck will definitely be outlasting me!!

Have been using Amsoil in my pickups and side by side with great success. 250,000 miles on last truck, still running strong when I traded it.

Promptly taken care of

Received my oil filters 3 weeks ago, still waiting for the oil, where is my oil?

I upgraded to this lubricant from Mobile 1. I noticed an improvement in my gas mileage and the performance of my Ford F-150 Supercrew with the 5.4 engine and a hair over 95,000 miles. I would definitely recommend AMSOIL.
